BACKGROUND

Medical equipment and instruments are required to maintain an aseptic condition in order to protect the safety and health of patients. With the advancement of science and technology, using electrical medical equipment has become more common. However, one problem associated with using electrical medical equipment includes difficulty with safely transporting equipment over long-distances, thereby compromising the safety and health of patients that require electrical medical equipment. Additionally, prior to being shipped, medical equipment and instruments are typically only charged between 10% and 50% of their full capacity. As such, in order to ensure medical operations are safely performed, medical equipment and instruments must be charged and require a sterile power supply. In the event of an unexpected or tragic incident, e.g., an earthquake, typhoon, blizzard, or widespread power outage, charging medical equipment may not be possible. Further, geographic locations that do not have access to an adequate power supply and/or sterile environment cannot fully charge medical equipment and instruments.

While mobile power supplies are available, existing power supply devices and methods of supplying power are not able to charge medical equipment and instruments located in a sealed and sterile environment. Rather, these power supplies and methods thereof are surrounded by dust and bacteria, and are susceptible to contact by harmful fluids. Accordingly, the sterility and safety of using these power supplies to charge electrical medical equipment and instruments is degraded and the service life is significantly reduced. Additionally, the patient's health can be compromised.

In at least one example, the package 700 can include a plurality of portable devices 100. One or more of the plurality of portable devices 100 can be received in a first tray and a second tray as discussed above. In some examples, a first tray can receive and secure a plurality of portable devices. In some examples, a plurality of first trays can each receive and secure one or more of the plurality of portable devices. First microbial barriers can each be arranged to seal corresponding first trays and maintain a sterile environment for the portable devices. For example, if only one first tray is included to receive a plurality of portable devices, only one first microbial barrier is included corresponding to the first tray. In at least one example, the chargeable batteries can be arranged inside of the portable devices. In some examples, the chargeable batteries can be arranged external to the portable devices and contained within the corresponding first trays. Second trays can each be operable to receive and secure corresponding first trays in the second trays. In some examples, a plurality of first trays may be received in one second tray. In some examples, one second tray may receive one first tray. Second microbial barriers can each be arranged to seal corresponding second trays and maintain a sterile environment for each of the portable devices. For example, if only one second tray is included, only one second microbial barrier is included corresponding to the second tray. If more than one second tray is included, more than one second microbial barriers can be included corresponding to the number of second trays. A package can receive one or more second trays and provide a sterile enclosure for the plurality of portable devices. Any combination of portable devices, first trays, and second trays can be included in the package. For example, the package, as discussed above, may include any number and/or combination of: (i) one first tray which is received in one second tray, (ii) a plurality of first trays received in one second tray. Within each of the first trays can include one or more portable devices. A power supply can be electrically connected with each of the portable devices such that the chargeable batteries of each of the portable devices are charged in the sterile environment.

In some examples, more than one portable device 100 can be received in a single first tray which is then received in a second tray. The package 700, along with any configuration of portable devices 100, first tray(s), and/or second tray(s), provides a sterile environment to charge the portable devices 100 either individually, together all at the same time, or any combination of portable devices 100. For example, the power supply can provide a charge to all of the portable devices until all of the portable devices are fully charged or charged to the desired amount. In some examples, the power supply can provide a charge to the portable devices as needed for each individual portable device.

The power supply can supply power to the chargeable batteries corresponding with the portable devices via any charging method and/or system as discussed herein. For example, the power supply can supply power to each of the chargeable batteries corresponding with the portable devices via a wireless charging station located external to the portable devices having a transmitter operable to transmit power wirelessly to a receiver secured in each of the portable devices. In some examples, the power supply can supply power to each of the chargeable batteries corresponding with the portable devices via wired connection. For example, the system can include a plurality of first connecting cables and a plurality of second connecting cables electrically connected to corresponding first connecting cables. The first connecting cables can be secured within the first trays and the second connecting cables can be secured within the first trays and the second trays. The power supply can be electrically connected with the second connecting cable to supply power to each of the chargeable batteries corresponding with the portable devices.

The charging method, i.e. wirelessly or wired, can be different between individual portable devices. In some examples, the charging method can be the same for all of the plurality of portable devices.

A charging system, for example charging system 1400 discussed herein, can maintain the chargeable batteries. The charging system can include a chip or a PCT to control a charge current to the chargeable batteries. In some examples, a fuse can be included to disconnect the chargeable batteries from the power supply when a fuse triggering event occurs. In some examples, each portable device or a combination of portable devices can be disconnected by corresponding one or more fuses. In some examples, one fuse can disconnect all of the plurality of portable devices at the same time.

In at least one example, the system can charge the plurality of portable devices intelligently to improve the lifespan and efficiency of the chargeable batteries. For example, the system can include a neural network to collect data and determine the time, length of charge, amount of power supplied, and other suitable aspects of charging the chargeable batteries. Also, the system can determine charge each portable device according to individual needs and requirements.

The neural network is a multi-layer deep learning network of interconnected nodes. Each node can represent a piece of information. Information associated with the nodes is shared among the different layers and each layer retains information as information is processed. In some cases, the neural network can include a feed-forward network, in which case there are no feedback connections where outputs of the network are fed back into itself. In some cases, the neural network can include a recurrent neural network, which can have loops that allow information to be carried across nodes while reading in input.

Information can be exchanged between nodes through node-to-node interconnections between the various layers. Nodes of the input layer can activate a set of nodes in the first hidden layer. For example, as shown, each of the input nodes of the input layer is connected to each of the nodes of the first hidden layer. The nodes of the hidden layer can transform the information of each input node by applying activation functions to the information. The information derived from the transformation can then be passed to and can activate the nodes of the next hidden layer, which can perform their own designated functions. Example functions include convolutional, up-sampling, data transformation, pooling, and/or any other suitable functions. The output of the hidden layer can then activate nodes of the next hidden layer, and so on. The output of the last hidden layer can activate one or more nodes of the output layer, at which point an output is provided. In some cases, while nodes (e.g., node) in the neural network are shown as having multiple output lines, a node has a single output and all lines shown as being output from a node represent the same output value.

In some cases, each node or interconnection between nodes can have a weight that is a set of parameters derived from the training of the neural network. For example, an interconnection between nodes can represent a piece of information learned about the interconnected nodes. The interconnection can have a numeric weight that can be tuned (e.g., based on a training dataset), allowing the neural network to be adaptive to inputs and able to learn as more data is processed.

The neural network can be pre-trained to process the features from the data in the input layer using the different hidden layers in order to provide the output through the output layer. In an example in which the neural network is used to identify objects in images, the neural network can be trained using training data that includes both images and labels. For instance, training images can be input into the neural network, with each training image having a label indicating the classes of the one or more objects in each image (basically, indicating to the network what the objects are and what features they have).

In some cases, the neural network can adjust the weights of the nodes using a training process called backpropagation. Backpropagation can include a forward pass, a loss function, a backward pass, and a weight update. The forward pass, loss function, backward pass, and parameter update is performed for one training iteration. The process can be repeated for a certain number of iterations for each set of training images until the neural network is trained enough so that the weights of the layers are accurately tuned.

For the example of identifying objects in images, the forward pass can include passing a training image through the neural network. The weights can be initially randomized before the neural network is trained. The image can include, for example, an array of numbers representing the pixels of the image. Each number in the array can include a value from 0 to 255 describing the pixel intensity at that position in the array. In one example, the array can include a 28×28×3 array of numbers with 28 rows and 28 columns of pixels and 3 color components (such as red, green, and blue, or luma and two chroma components, or the like).

For a first training iteration for the neural network, the output can include values that do not give preference to any particular class due to the weights being randomly selected at initialization. For example, if the output is a vector with probabilities that the object includes different classes, the probability value for each of the different classes may be equal or at least very similar (e.g., for ten possible classes, each class may have a probability value of 0.1). With the initial weights, the neural network is unable to determine low level features and thus cannot make an accurate determination of what the classification of the object might be. A loss function can be used to analyze errors in the output. Any suitable loss function definition can be used.

The loss (or error) can be high for the first training images since the actual values will be different than the predicted output. The goal of training is to minimize the amount of loss so that the predicted output is the same as the training label. The neural network can perform a backward pass by determining which inputs (weights) most contributed to the loss of the network, and can adjust the weights so that the loss decreases and is eventually minimized.

A derivative of the loss with respect to the weights can be computed to determine the weights that contributed most to the loss of the network. After the derivative is computed, a weight update can be performed by updating the weights of the filters. For example, the weights can be updated so that they change in the opposite direction of the gradient. A learning rate can be set to any suitable value, with a high learning rate including larger weight updates and a lower value indicating smaller weight updates.

The neural network can include any suitable deep network. One example includes a convolutional neural network (CNN), which includes an input layer and an output layer, with multiple hidden layers between the input and out layers. The hidden layers of a CNN include a series of convolutional, nonlinear, pooling (for downsampling), and fully connected layers. In other examples, the neural network can represent any other deep network other than a CNN, such as an autoencoder, a deep belief nets (DBNs), a Recurrent Neural Networks (RNNs), etc.

Neural network can also be used to perform deep learning. In this example, the neural network includes an input layer, a convolutional hidden layer, a pooling hidden layer, fully connected layers, and output layer. The neural network can identify specific environmental features (e.g., humidity, temperature, amount of charge, number of portable devices, etc.) in an image. First, each feature is considered as a neuron that has learnable weights and biases. Each neuron receives some inputs, performs a dot product and optionally follows it with a non-linearity function. The neural network can also encode certain properties into the architecture by expressing a single differentiable score function from the data on one end to class scores at the other to extract specific environmental features from the target image. After identifying features as specific environmental features, the neural network can generate a mean score (or z-score) of each feature and take the average of the scores within the user-defined buffer.
